Well, I did say "necessary", and not "sufficient". But yes, moving
inodes, especially if the inode is currently open gets interesting. I
don't think there are that many user space applications that would
notice or care if the st_ino of an open file changed out from under
them, but there are obviously userspace applications, such as tar,
that would most definitely care.
